Application filed June 6,1907. Serial No. 377,566.

To all whom it may concern:

Be it known that 1, Jesse G. ROSEBOOM, a citizen of the United States,residing at Norfolk, in the county of Norfolk and State of Virginia,have invented new and useful Improvements in Sash-Frames and Sashes, ofwhich the following is a specification.

My invention relates to sash frames and sashes, and more particularly tothose designed to be made of metal; and it has for one of its objects toprovide a sash frame, a sash, a wind-guard movable with the sash, and acounterbalance weight, all so constructed and relatively arranged thatthe wind-guard and weight may be readily placed in position, and whennecessity demands ready access may be had to the wind-guard and weightfor repairs or other purposes.

Another object of the invention is the provision of a sash-balancingweight in the form of a case contain-.

ing heavy material, either in one piece or in bulk, and provided with adischarge opening controlled by a fusible closure, this in order thatwhen the lower sash is in its upper position and a fire takes place, theheat will melt the fusible closure and permit the heavy material togravitate out of the case and thereby enable the sash to drop to itsclosed position.

Another object is the provision of an upper sash containing heavymaterial in comminuted form and provided with a discharge opening forsuch material and a fusible closure for such opening, so that when alire occurs while the upper sash is in its lower posi tion, the fusibleclosure will be melted and the heavy material permitted to pass from thesash with the result that the ordinary or any other suitable weightscomplementary to the sash will raise the same to its closed position.

Another object is the provision of means in the lower portion of a framestile designed to cooperate with a sash-balancing weight with a view ofpreventing the weight as it passes down toward the lower end of thestile from swinging out of the stile.

With the foregoing in mind, the invention will be fully understood fromthe following description and claims when the same are read inconnection with the accompanying drawings, forming part of thisspecification, in which:

Figure 1 is a vertical section illustrating a sashframe and sashesconstructed in accordance with my invention. Fig. 2 is a horizontalsection taken through the frame and sashes. Fig. 3 is a broken sectionalperspective view, on an enlarged scale, showing the relative arrangementof the frame, the lower sash, a wind-guard, a counterbalance-weight andthe cable intermediate the wind-guard and the counterbalance weight.Fig. 4 is a sectional view of one of the counterbalance-weightscomplementary to the lower sash. Fig. 5 is a detail section, on anenlarged scale, showing the discharge opening of the upper sash, theheavy comminuted material in said sash, and the fusible closure of theopening. Fig. 6 is a detail section showing a guide for onecounterbalance-weight of the lower sash. Fig. '7 is a detail sectionshowing the connection of one cable of the lower sash to the mud guardthereof.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A A are the side stiles of a metallic sash frame. These stiles arejoined to a head and a sill in the ordinary or any other suitable mannerand are provided with two guideways a and b; the former being for thelower sash and the latter for the upper sash.

B is the lower sash, and O is the upper sash. The

lower sash B is provided in the outer sides of its vertical bars withgrooves c and is also provided at the upper ends of said grooves withapertured plates (1 for a purpose presently set forth. D D arewind-guards, preferably of I-form in crosssection, arranged in theopposed grooves a and c of the stiles A and sash B, respectively, andunder the plates (1 of said sash.

E E are the counterbalance-weights complementary to the sash B; saidweights being located in the outer portions of the wind-guards; and F Fare cables, preferably cords as shown, extending between and connectedto the wind-guards D and weights E and also extending over sheaves orpulleys G, mounted in the upper portions of the side stiles A. or elsein the head of the frame, as shown. The wind-guards D bear at theirupper ends against the undersides of the plates d on sash B, and henceit will be apparent that when the sash is raised, the gravitation of theweights E by pulling the windguards D upward will render easy theraising of the sash. It will also be apparent, in this connection, thatwhen sash B is moved downward, the wind-guards D will also be moveddownward and the weights E will be raised, with the result that theweights will balance the sash.

By virtue of the construction and relative arrangement of the partsdescribed, it will be seen that the weights, wind-guards and sash may beexpeditiously and easily arranged in the frame; also, that whennecessary for repairs or any other purpose ready access may be gained tothe weights. The wind-guards D extend the full height of the sash B,and, as their name implies, serve to preclude the passage of drafts ofair between the sash and the stiles A.

As best shown in Fig. 4, the weights E respectively comprise a case 6having a discharge opening f in its lower end or at any other suitablepoint, heavy material g, preferably though not necessarily in acomminuted state, arranged in the case e, and a fusible closure it whichunder normal conditions serves to retain the heavy material in the casee'i. 6., against dropping through the opening f. When, however, a fireoccurs in the vicinity of my improved sash frame and sashes, it will beseen that the fusible closures h of the weightcases 6 will be melted,whereupon the heavy material g will pass from said cases a. Inconsequence of this the sash B will gravitate to its closed position,and in that way close the window and lessen the liability of the firespreading.

With a view of preventing swinging oi the weights E as the same approachthe lower ends of their traverse, I provide in the grooves a of thestiles A, fixed vertical rails H of T-iorm in cross section, the headsof which are arranged to enter correspondingly-shaped grooves I in theouter sides of the weight cases 0. Thus when the Weights E approach thelower ends of the stiles A there is no liability of the weights swingingout of the stiles.

J J are the wind-guards complementary to the upper sash C.

K K are the weights for the upper sash, and L L are cables passed oversheaves M mounted in the upper portion of the sash frame and connectingthe weights K and the wind-guards J. The stiles A, sash 0, windguards J,Weights K, and cables L are relatively arranged in the same manner asthe stiles A, sash B, Windguards D, weights E and cables F, and need nottherefore be described, except to say that the wind-guards J bearagainst apertured plates similar to the plates d at the upper ends ofthe grooves of sash G, and the weights K may be and preferably are ofthe ordinary Well known type.

The upper sash C is peculiar in that its lower, hollow bar at containsheavy material n in a comminuted state, and is provided with an openingp normally closed by fusible material q. From this it follows that inthe event of fire in the vicinity of my improvements While the sash G isin its lower or open position, the closure q will be melted, when theheavy material n will pass through the opening p until the sash O islighter than its weights K when the weights will obviously raise thesash O to its closed position and in that way tend to prevent the spreadof the fire.

In addition to the practical advantages hereinbefore ascribed to myimproved metallic sash frame and sashes, it will be noted that thestructure as a whole is compact and neat in appearance, and, at the sametime, is well adapted to withstand the usage to which sash frames andsashes are ordinarily adapted.

While designed more particularly for use in metallic sashes and sashframes, I desire it understood that such of my improvements as areapplicable may be used in sash frames and sashes of wood or any othermaterial Without involving departure from the scope of my invention asclaimed.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

1. The combination of the side stile of a sash frame; said stile havinga vertical groove or guide-way at its inner side, a sheave mounted inthe frame, a vertically slidable sash having a groove in the outer sideof its side bar and also having an apertured arm at its upper end, averticallymovable guard, of I-form in cross-section, arranged in theopposed grooves of the stile and sash and under the overhanging arm ofthe latter, a weight movable in the outer portion of the guard, and acable passed over the sheave and through the overhanging arm of the sashand connecting the guard and the weight.

2. The combination of a sash frame, a vertically slidahle sash, a cableconnected to the sash and pased over a sheave, and a weight connected tothe cable and comprising a case having a discharge opening, a fusibleclosure therefor, and heavy material contained in the case and adaptedwhen said fusible closure is melted to drop from the case.

3. The combination of the side stile of a sash frame, a Trail fixed inthe lower portion thereof, a vertically slidable sash, a sheave, a cablepassed over the sheave and connected to the sash, and a weight connectedto the cable and movable in the stile and having a correspondinglyshaped groove arranged to receive the said T-rail.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JESSE G. ROSEBOOM.
